IMPROVEMENT IN AXLES.

Specification forming part of Letters Patent No. 162,729, dated April 27, 1875; application filed November 14, 1873. I i

' is a longitudinal section of the thimble-skein.

Fig. 3 is a cross-section of the skein-arm and tenon. Fig. 4 is a sectional view of a skcin with box in place. Fig. 6 is a sectional view of the top of bolster or sand-board.

The same letters refer to same parts in all the drawings.

In Fig. 1, A is the axle; B, the bolster. c c c are the reach and hounds. D D are the standards. E E are the thimble-skeins. FF are the arms, with shoulder-flanges L, as seen in Fig.

3, for the bolster to rest upon. The arm F extends upward through the bolster in form of tenou 0, as is seen in Fig. 3, and may terminate flush with the upper face of the bolster B or form-brace K, as seen in Fig. 1. 5 5 are the spindles or journals for the wheels to turn upon. H is the tension-rod. 3 3 are lugs cast upon the lower wall of the thimhle-skein, with holes for the tension-rod H to pass through. J J are recesses upon thejournals 5 5. 1 1 1 are washers or eyes formed on the ends of hounds, under braces, and are placed between axle A and tension-rod H, and are made of sufficient thickness to bring the tension-rod H on a line with the openings in lugs 3 3, so that the tension-rod may rest upon a line between the lugs 3 3, in order that it may receive a heavy tensile strain without affecting the other parts. Bolts pass down through the bolster B, hounds c c c, axle A, Washers 1 1 1, and tension-rod H, and hold all the parts together by means of screwthreads and nuts. By this arrangement, the

strain falling upon one skein is not communicated to the other, but falls upon the intermediate bolts. Tension-rod H passes through the holes in lugs 3 3, and is made tight by means of screw-threads and nuts upon its outer ends. Fig. 2 shows the central and inside structure of the thimble-skein and its adjuncts. Fig. 3 shows-the relative position of the thimble-skein E, arm F, flanges L, and tenon 0. Fig. 4: shows a skein of form long known and used, upon which I construct a large shoulder, 7, upon the upper part of the inside, at the shoulder of the spindle, for the axle A torest against, and'lug 3 upon its lower wall. 2 2 show the walls of the box to be fitted in the hub of wheel to turn on the journal 5, and. is a cylindrical tube tapered to conform to the journal. This figure also shows the recess J, as related to the box 2. In this skein the shoulder 7, when made large, and axle A are fitted to it, in combination with lug 3, and tension-rodHforms a truss, that secures greater strength and less liability to bend or spring than the 01d methods of construction of wagonaxles. Fig. 6 shows the bolster or sandboard B, with the slot-opening for tenon O, or tenon 0 and standard D. A strap-band is passed around the end of the bolster B or sandboard, and secures the parts in place. Recess J is formed upon the spindle 5, instead of within the box 2, as heretofore, and secures a more perfect flow of oil to the places of contact or hearing. The box 2, when fastened in the wheels, is secured on the spindles 5 by means of nut-Washers and screw-threads,

linchpins, or other suitable device, none of which are shown. Y.

What I claim, and desire to -secure by Let ters Patent, is-

1. Axle A, bolster B, thimble-skein E, lugs 3 3, and tension-rod H, in combination with arm F, tenon O, and flanges L, as set forth.

2. The combination of the axle, hound,bolts washers 1 1 1, tension-rod H, lugs 3 3, as set forth.
